Thanks for checking with us in Apple Communities, Jmejia1314. That's a very good question.
I see you're wondering about the possibility of combining multiple iOS backups. Since each back up is basically a snapshot of your device at the time you've backed up, there isn't any way to merge them. You could restore the back up that has most of the information you need then recreate the information that's missing though.
To help you determine what's best to use for you, have a look here: About backups in iCloud and iTunes
Take care!
